Power Quality

Product Knowledge

Power Quality (PQ) covers a wide range of issues, from voltage disturbances like dips, swells, interruptions and transients, to current harmonics, to perfor-mance wiring and grounding. The symptoms of poor PQ include intermittent lock-ups and resets, corrupted data, premature equipment failure, overheating of components for no apparent cause, etc. The ultimate cost is in downtime, decreased productivity and frustrated personnel.

As we connect more electronic devices to our power systems, the “quality” of the power becomes more important. Quality can be defined in many ways. Stable voltages and undistorted waveforms are two characteristics which are very desirable in power systems. Grounding affects voltage stability, and more importantly, is critical to personal safety.

A technique to analyze the current drawn by computers, electronic ballasts, variable frequency drives and other equipment, harmonics are a mathematical model we use to analyze distorted waveforms in the real world.

The utilities do a wonderful job of generat-ing a clean voltage sinewave with constant amplitude and frequency. But when this voltage is applied to a device, Ohm’s Law kicks in.

Linear SystemsMost devices that consume power, incan-descent lamps, heaters and many motors are linear, creating a current sinewave very similar in shape to the voltage sinewave.

Non-Linear SystemsHowever, some modern equipment is non-linear, computer power supplies, variable frequency drives, electronic ballasts and unin-terruptable power supplies. Because the load characteristics of these consumers constantly change, the current waveform also changes, no longer mirroring the voltage waveform.

These waveforms are described as non sinusoidal. The voltage and current waveforms are no longer simply related — hence the term “non linear.”

As voltage is applied to an electronic power supply, the current drawn is (approximately) zero until a critical “firing voltage” is reached on the sinewave. At this firing voltage, the diode (an electronic switch) turns on allow-ing current to be conducted. This current increases over time until reaching the peak of the sinewave, then decreasing until reaching the firing voltage in the negative going direc-tion. This process then reverses for the next cycle creating a series of positive and nega-tive pulses instead of a clean sinewave.

Power analyzers use a mathematical series of sinewaves of varying frequencies and amplitudes to model this series of pulses. The frequencies we use are multiples of the funda-mental frequency, 60 Hertz. We call these multi-ple frequencies harmonics. The second harmonic is two times 60 Hertz, or �20 Hertz; the third harmonic is �80 Hertz, and so on. Under normal conditions for a balanced linear load, the funda-mental 60 Hz portion of the phase currents will cancel in the neutral conductor.

In three-phase power systems, the “even” harmonics (second, fourth, sixth, etc.) cancel, the only important ones are the “odd” harmonics. Certain odd numbered harmonics called triplens (odd multiples of the third harmonic: 3rd, 9th, �5th etc.) do not cancel, but rather add together in the neutral conductor.

These harmonic current pulses, if they are large enough, will begin to distort the voltage waveforms in the building and may cause premature failure of electronic devices, and will create heat on the conductors. This rise in tempera-ture of the neutral conductor can overheat the surrounding conductors and cause insulation failure. These currents will also overheat the transformer sources which supply the power system. This is the most obvious symptom of harmonics problems; overheating neutral conductors and transformers.

Symptoms of harmonics usually show up in the power distribution equipment that supports

the non-linear loads. There are different types of non-linear loads but we will consider just two, single-phase, and three-phase. Single phase non linear loads are prevalent in offices, while three phase loads are widespread in industrial plants.

Each component of the power distribution system manifests the effects of harmonics a little differently. Yet all are subject to damage and inefficient performance.

If you were to listen to an ordinary 60-cycle power line, you would hear a monotone hum. When harmonics are present, you hear a different tune, rich with high notes. Harmon-ics in electrical panels can play a lively tune as well. Panels that are designed to carry 60 Hz currents can become mechanically resonant to the magnetic fields generated by higher frequency harmonic currents. When this happens, the panel vibrates and emits a buzzing sound at the harmonic frequencies.

Other symptoms include: • Nuisance tripping of circuit breakers • Malfunction of UPS systems and

generator systems • Metering problems • Shortened life span • Computer malfunctions • Overvoltage problems

Telecommunications systems often give you the first clue to a harmonics problem. Telecommunications cable is commonly run right next to power cables. To minimize the inductive interference from phase current, telecommunications cables are run closer to the neutral wire. Triplens in the neutral conductor commonly cause inductive interference, which can be heard on a phone line. This is often the first indication of a harmonics problem and gives you a head start in detecting the problem before it causes major damage.

Symptoms and their effectsIn most cases, a power quality problem will exhibit certain symptoms and generate system effects that can be monitored for diagnosis. But, be careful; just because a piece of equip-ment seems to be working properly on a daily basis doesn’t mean that there aren’t any PQ problems at the given location. For example, a low rms line voltage may be present, one that’s being compensated for by the built in voltage regulation capability of some types of load equipment, such as where a switching mode power supply (SMPS) is in use. This kind of situation may go unnoticed for a long period and then be exposed during a time when the electric utility provides reduced voltage for some reason. Then, the SMPS will

be unable to compensate, and the equipment will malfunction.

Low rms line voltageLow rms line voltages typically cause a rise in current on circuits where voltage-regulat-ing types of equipment are being served. An SMPS is a good example of this. Higher than normal operating current may cause overheat-ing in connections, sometimes in conductors, and can cause excess heat in overcurrent protective devices with nuisance tripping of circuit breakers.

Motors take longer to start and have less torque when the line voltage is low. This may place stress on motor controllers and the motors themselves. Nuisance tripping during startup is possible with low rms line voltage as well.

High rms line voltageNormally high rms line voltage has little harmful effect on most voltage regulating equipment, since the result is actually a decrease in input current. This also means that less current is needed to be trans-ported via the wiring and through the overcur-rent protective devices serving such loads.

However, motors and transformers that have high rms line voltage applied to them are negatively affected: They overheat and begin to produce harmonic currents due to magnetic saturation of the ferrous metals used in their cores or stators. Motors will draw excessive running current, placing stress on all of the supply wiring circuits and overcurrent protective devices.

Any equipment that can’t self compen-sate for a high rms line voltage (e.g., like a voltage regulator) will generally suffer a significantly shortened life span due to excess running current and associated higher operating temperatures. Linear loads, espe-cially lighting systems, are usually affected in this manner.

Voltage dipsWhen the rms line voltage experiences a momentary reduction for any amount of time a dip has occurred. This often produces no noticeable effects, unless the line voltage was already on the low side of nominal when the dip occurred, and then only if the sag was a deep one. However, dips are well known to

Neutral bus bars and connecting lugs are sized to carry the full value of the rated phase current. They can become over-loaded when the neutral conductors are overloaded with the additional sum of the triplen harmonics.

cause AC coil contactors to either chatter or to completely dropout, resulting in their loads being highly affected or shutdown. Motor controllers are especially susceptible to this kind of problem, unless they’ve been specially designed to have immunity to dips.

Voltage swellsWhen the rms line voltage experiences a momentary increase for any amount of time a swell has occurred. The term “surge” was at one time used to describe what is now called a swell. A swell often produces no noticeable effects, unless the line voltage was already on the high side of nominal when the swell occurred, and then only if the swell is a high one.

Lighting systems are usually quite suscep-tible to swells, as are AC DC power supplies. A swell can often trigger operation of an overcurrent protective device if it was being operated near its limit at the time of the swell.

TransientsThere are two origins for the transients that occur in a power system: lightning tran-sients and switching transients.

Lightning transients occur when a light-ning bolt strikes between a cloud and objects on earth. The effect can be direct, injection of the lightning current into the object, or indirect, inducing a voltage into electrical circuits.

Transients usually travel by way of the wires, power or telephone and cable. Protec-tion of the house against the direct effects of lightning is done by proper grounding techniques and through ground rods. Note that “lightning rods” are intended to protect the structure of the house and avoid fires but do not prevent transients from occuring.

Direct lightning effects are limited to the object being struck and its surroundings, so that the occurrence is considered rare but it is nearly always deadly for persons or trees. Well-protected electrical systems can survive a direct strike, perhaps with some momentary disturbances from which they recover (blink-ing lights and computers restarting during a lightning storm).

Indirect lightning effects are less dramatic than from a direct strike, but they reach further out, either by radiating around the strike, or by propagating along power lines, telephone infrastructures and cable TV. From the point of view of the home dweller, unwanted opening of the garage door, or a surge coming from the power company during a lightning storm, would be seen as indirect effects.

Switching transients occur any time a large electrical load is turned on or off it generates a switching surge. This surge

is similar to a lightning strike only much smaller. What this surge lacks in size it makes up for in frequency. These switching transients occur hundreds, if not thousands of times per day.

Switching transients occur when electri-cal loads are turned on or off within your home, as well as by the normal operations of the power company. Refrigerators, freez-ers, furnaces, vacuum cleaners, well or sump pumps, washing machines, dish washers and even electric hand tools can all cause switch-ing transients. Over a period of time the small but continuously occurring transients will slowly wear out the electronic equipment.

There are two things that can protect sensi-tive equipment from switching transients, install internal surge suppression devices and/or isolate them on a dedicated circuit.

An analogy often given is the “water hammer” that can occur in your water pipes if a faucet is turned off too quickly: the electric current flowing in the wires tries to flow for a short time after the switch has been opened, producing a surge in the wiring, just like the surge of pressure in the plumbing.

Power Quality Analyzers

The main objective of an engineer trouble-shooting a power quality event is to identify the source of the disturbance in order to determine the required corrective action. To identify the source, the engineer depends on recorded data captured by monitoring equipment.

For the facilities manager or power qual-ity department, this is an excellent tool for monitoring power quality in a plant to prevent costly shutdowns and work stoppages.

Electronic equipment is damaged more often by power disturbances than by fire, theft,

and vandalism combined. Intermittent power problems are the most expensive hidden expense to the owners of microprocessor based equipment.

Budgets are tighter than ever and more output is expected from each engineer, so tools that provide a broader range of capabilities have a special value. Instead of the choice between buying a power quality analyzer or a new data acquisition system, engineers can have both--and at a greatly reduced price and size.

Frontline troubleshooting and predictive maintenanceThis application is typically performed by a member of the maintenance team at a facility in response to failures that may result in downtime.

Because the facility is down and not generating revenue, there is extreme urgency to get the problem identified so the operation can be restored without further interruptions. Therefore, the maintenance tech wants to see the information, on the problem, on the screen of the tool (opposed to recording it and analyzing the data with a PC – later on).

Symptoms include:• Overheating transformers• Overheating motors• Reduced operating life of motors & transformers• Nuisance tripping “Circuit breakers, etc..”

Load studiesThis application is conducted before the installation of new loads to determine if the system has enough electrical capacity to handle the proposed loads.

The 3 groups that conduct this study:• First, an electrical contractor hired to install

new equipment• Second, if equipment is installed by the

maintenance team, they may do the load study themselves

• Third, the utility will perform the load study* to determine what transformers and other equipment are necessary for a newly constructed facility, one that will draw power from their grid

*In the US there is a regulation call NEC ��0.87 that defines how to properly perform a load study in order to obtain a permit.

Energy auditsThis is done in order to reduce the cost of electricity. These costs include the charge per kilowatt hour, plus the penal-ties for power factor and peak demand. The test is performed over a period that captures a representative energy profile of the business in question. This could be a day, week or month depending on the industry. Once this test is performed the facility will improve their energy consumption (i.e.: high efficiency equip-ment or power factor correction). Next, the test will be repeated to validate the benefit of these changes.

Voltage qualityUtilities are expected to supply voltage to their customers that meet a minimum level of quality, power that allows their customer’s facility to run without problems. When a customer experiences a voltage quality issue they often assume that the utility is at fault, so the customer or the utility will use a tool to validate the voltage quality at the service entrance. After the utility has been ruled out, voltage quality tests are conducted inside the facility and at the load.

Symptoms: • Flicking lights• Outages• Uninterruptible power supply (UPS) cycling

Long term / intermittent analysis:Often times there are problems that can’t be found immediately, this is because they are caused by the interaction of different loads on the power system. In this case it’s benefi-cial to have an instrument with the ability to record voltage and current information over time. To pinpoint the root cause of the disturbance, these tests usually use multiple instruments to record at a variety of loca-tions simultaneously. Tests that often last for months while they wait for the symptom to occur, allowing correlation to a specific event that caused the problem.

Symptoms include:• Intermittent voltage disturbances• High speed transients
